restart_presto_engine

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It only says 'Restart' without explaining side effects (e.g., impact on running queries, permissions required, or whether restart is graceful). This is insufficient for a mutation operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short (2 lines) but includes a docstring structure (Args, Returns) that is acceptable though not necessary. It is not verbose, but the lack of essential information makes it merely adequate in length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (1 required param, no annotations, sibling tools with similar actions), the description is incomplete. It does not mention potential outcomes, error conditions, or any context beyond the basic restart intent. An output schema exists but is not utilized in description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description should compensate. It merely restates 'engine_id: Engine identifier', adding no meaning beyond the schema's string type and required flag. No format, constraints, or examples are given.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states 'Restart a Presto engine in watsonx.data', which is a specific verb (restart) and resource (Presto engine). It clearly distinguishes from sibling tools like restart_prestissimo_engine, pause_presto_engine, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use restart vs alternatives (e.g., pause/resume) or any prerequisites. It lacks any context about conditions or preferred use cases, failing to help the agent decide.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
